COMBINED FIRE-BOX, GRATE, AND SIFTER FOR STOVES.

SPECIFICATIQN forming part of Letters Patent No. 317,901, dated May 12, 1885.

1 Application filed February 7, 1884. (No model.)

To ctZZ whom it may concern:

Be it known that 1, Isaac JoNEs Warns, of Nanuet, in the county of Rockland and State of New York, have invented a new and useful Improvement in Combined Fire-Boxes, Grates, and Sifters for Stoves, Ranges, and Heaters, of which the following is a full, clear, and exact description. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of my improvement shown as applied to a stove, partly in section, and parts being broken away. Fig. 2 is a sectional side elevation of the same, taken through the line 00 m, Fig. 1. Fig. 3 is a sectional front elevation ofthesame,taken th rough the broken line 3 y y, Fig. 2, and parts being broken away. Y

The object of this invention is to promote convenience in controlling fires in stoves, ranges, and heaters.

The invention consists in a combined fire- 2 box, grate, and sifter constructed with gratebars having their rear parts extended upward and in contact, and secured in place by a hooked plate secured to the bottom wall of the top flue to form the rear wall of the fire-box, and provided with a bar having alternating lugs upon its opposite sid s for agitating the said grate-bars. The front wall of the firebox is formed of bars having their upper parts in contact and provided with hooks at their upper ends to hook upon a' suspending bar secured in the forward part of the firechamber. Beneath the grate-bars is placed the sifter having inclined slots engaging at its rear edge with a hooked flange formed upon the rear wall of the fire-chamber, and suspended from the center grate-bar by a hooked rod, so that the said sifter will be jarred by the movements of the grate-bars, as will be hereinafter fully described.

I will show and describe my improvement as applied to a stove, but do not limit myself to that application, as it can be used with equal advantage in ranges and heaters.

A represents an ordinary cooking-stove. B are the grate-bars, the inner parts of which are bent upward to fit against the rear side of the firechan1ber of the stove and form the back of the fire-box. The upper parts of the grate-bars B fit closely against each other to keep the fire from coming in contact with the back of the fire-chamber and injuring it. The spaces between the lower parts of the gratebars upon which the fire rests gradually increase in width downward, so that they will not be liable to become choked with cinders.

The upper ends of the grate-bars B are rounded off, and have a groove in their forward sides to receive the hooked flange of the plate'O, which rests upon the bottom plate of the top fine of the stove, and has openings formed through it to receive lugs D, formed upon the said flue-plate and perforated to receive the keys E, by which the said plate 0 is secured in place upon the said lugs.

In a recess, 0, in the back plate of the firechamber or near the lower ends of the upwardlyprojecting rear parts of the grate-bars B, is placed a bar, F, having lugs G, formed alternately upon its opposite side, and equaling the said grate-bars in number. The ends of the bar F revolve in bearings in the side plates in the stove, and one end of the said bar projects and is squared to receive a crank for revolving the said bar. YVith this construction, by revolving the bar F, the alternate gratebars B will be successively raised a little and allowed to drop, jarring out the ashes and cinders, which fall upon the sifter H, placed at a little distance below the said grate-bars B.

The sifter H is formed of a plate having slightly-inclined slots formed in it extending from its forward edge nearly to its rear edge, which slots increase in width from the upper surface of the said plate to its lower surface,

so that the said slots will not be liable to become choked. The rear edge of the sifter H is extended upward, is rounded, and has a groove along its forward side to receive the hook-edge of the flange 1, formed upon the rear wall of the fire-chamber.

The sifter H is supported by the rod J, the upper end of which is hooked into alug formed upon the lower side of the central grate-bar B. on a bar joining the central arms of the sifter H. The hooked rod J is placed in the rear of the central line of the sifter, so that the forward part of the said sifter will be heavier IOO than the rear part, and will thus keep the rear edge of the said sifter in gear with the hooked flange I.

With this construction, as the grate-bars B are jarred by the bar F, to shake out the ashes, the sifter H will also be jarred to cause the ashes to pass through it into the ash-pan K, placed beneath the sifter, while the cinders slide down the said sifter and fall from its lower edge into the cinder-pan L, placed below the said edge at the front of the ash-pan K.

The front of the fire-box is formed of bars M, the upper parts of which fit against each other, and the lower parts of the said bars are narrowed to leave spaces between them. The bars M extend down nearly to the ends of the grate-bars B, and upon their upper ends are formed hooks to hook upon a bar, N, crossing the forward part'of the fire-chamber, and secured at its ends to or formed upon the end walls of the said fire-chamber. With this construction one or more of the front bars M can be readily raised with the poker when it is desired to remove cinders too large to pass beneath the ends of the said bars when hanging in place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A combined fire-box, grate, and sifter, constructed substantially as herein shown and described, and consisting of the grate-bars B, having their rear parts extended upward and in contact to form the rear wall of the fire-box, the shaker-rod F, having lugs G, the front bars, M, having hooks at their upper ends, and the sifter H, suspended from the grate, as

set forth.

2. The combination, with the rear wall of the fire-chamber and the bottom plate of the top flue, of the grate-bars B, having their rear parts extended upward and provided with rounded and grooved upper ends, and the hooked plate 0, substantially as herein shown and described, whereby the said grate-bars 4. A fire-box having its front bars, M, made separate and each provided with a hook at its upper end for suspending it, whereby any one of the said bars can be raised independently of the others for the removal of cinders, substantially as herein shown and described.

5. The combination, with the rear wall of the fire-chamber having hook-flange I and the grate-bars B, of the sifter H, having inclined slots, and the suspended hooked rod J, substantially as herein shown and described, whereby the said sifter is suspended from the grate-bars and will be jarred by the movements of the said bars, as set forth.
